3 Minutes With Kent

This is an answer to a question on my AMA (https://github.com/kentcdodds/ama/issues/331) about babel-preset-env (https://github.com/babel/babel/tree/master/experimental/babel-preset-env). Links: - browserslist (https://github.com/ai/browserslist) - The library babel-preset-env uses to know what browsers support.

Here's another answer to a question on my AMA (https://github.com/kentcdodds/ama/issues/330). Links: - How getting into Open Source has been awesome for me (https://blog.kentcdodds.com/how-getting-into-open-source-has-been-awesome-for-me-8480cd756a80)

This is an answer to this question on my AMA (https://github.com/kentcdodds/ama/issues/328). Links: - Why semver ranges are literally the worst (https://blog.kentcdodds.com/why-semver-ranges-are-literally-the-worst-817cdcb09277) - semver.npmjs.com (https://semver.npmjs.com/)

My answer to this question on my AMA (https://github.com/kentcdodds/ama/issues/327).

Someone asked me some questions about using React and here are my answers :)

In this episode, I talk about my blogpost Newspaper Code Structure (https://medium.com/@kentcdodds/newspaper-code-structure-8b4616af9539) and Function Declarations (https://javascriptweblog.wordpress.com/2010/07/06/function-declarations-vs-function-expressions/). Enjoy!

I had a friend send me this testing code: describe('handleChangeStatusConditionSearchText', () => { test('should handle changing status search text within FormWizard', () => { const wrapper = shallow(); const state = { ...wrapper.instance().state, statusConditionSearchText: 'poop' }; wrapper.instance().handleChangeStatusConditionSearchText('poop'); expect(wrapper.instance().state).toEqual(state); }); }); And I had a few concerns with it, so I decided to record my thoughts :) (Learn more about enzyme (https://github.com/airbnb/enzyme) and shallow rendering (https://github.com/airbnb/enzyme/blob/f3bbfd3c2b1ae5c09d50fa0429d0dd599d3bbe82/docs/api/shallow.md), and then never shallow render again...

Just some ramblings for my personal feelings around classes in JavaScript. I'd much rather just use objects and closures :)

Some brief and deeper thoughts about Wicked (http://wickedthemusical.com/).

Just some thoughts about why I open source my stuff by default. Links: generator-kcd-oss (https://github.com/kentcdodds/generator-kcd-oss) How getting into Open Source has been awesome for me (https://medium.com/@kentcdodds/how-getting-into-open-source-has-been-awesome-for-me-8480cd756a80) Have a nice day!

I had a friend help me out on a project last night. His PR had a few linting issues so I asked him to fix some of them and later saw him on twitter expressing frustrating that ESLint can get in the way of building stuff. I agree with him to a point. This is how I feel about ESLint. Links: - ESLint (http://eslint.org/) - eslint-config-kentcdodds (https://github.com/kentcdodds/eslint-config-kentcdodds) See you all around!

Back in January, James Long (https://twitter.com/jlongster) introduced us (http://jlongster.com/A-Prettier-Formatter) to his new JavaScript code formatting tool prettier (https://github.com/prettier/prettier). It gained popularity quickly and just two days later I released prettier-eslint (https://github.com/prettier/prettier-eslint). Since then, a bunch of tooling has been built around these tools to make the experience and workflow really awesome. I'm excited to say that we're now using it on my team's project at PayPal! In this brief, I talk a bit about the challenges we've faced so far adopting prettier-eslint. Fun stuff!

Here's a quick synopsis of my blog post "An Argument for Automation" (https://medium.com/@kentcdodds/an-argument-for-automation-fce8394c14e2). I also talk about my yeoman (http://yeoman.io/) generator kcd-oss (https://github.com/kentcdodds/generator-kcd-oss) which has been really influential in me getting new high quality projects spun up really quickly. See yah!

I created a library (https://github.com/kentcdodds/babel-plugin-tester/blob/master/README.md) to make the testing lesson of my babel egghead course easier (to learn and teach).

One of my best internet friends Sarah Drasner (https://twitter.com/sarah_edo) recently tweeted (https://twitter.com/sarah_edo/status/864126183570591744) something really nice about me: IMHO the contributions @kentcdodds (https://twitter.com/kentcdodds) makes are huge because he teaches people how to contribute to OSS. That's time investment that scales

I get a lot of questions (https://github.com/kentcdodds/ama/issues/275) about when it's appropriate to use Jest snapshot testing, or why you wouldn't use snapshots for pretty much everything. This brief is my answer. If you're unfamiliar with Jest snapshot testing, it's really great and you can learn about what it is and how it works here (https://egghead.io/lessons/javascript-use-jest-s-snapshot-testing-feature?pl=testing-javascript-with-jest-a36c4074). I hope this is helpful! See you around!

This is another answer to a question (https://github.com/kentcdodds/ama/issues/254) on my ama (https://github.com/kentcdodds/ama): "Why not use a scoped package for nps?"

Just some thoughts on how to structure tests (specifically setup) in a way that makes them easier to understand in the future.

I got a question (https://github.com/kentcdodds/ama/issues/246) on my AMA (http://kcd.im/ama) asking me how to learn new tech and work on side projects. Here's my answer.

I got a question (https://github.com/kentcdodds/ama/issues/249) on my AMA (http://kcd.im/ama) asking me how I read and learn codebases. Here's my answer! See you all on twitter (https://twitter.com/kentcdodds)!
